Kawasaki mule starts and idles but won’t rev up

[JonR]

I need help! Kawasaki mule diesel starts an idles just fine, but it won’t rev up any RPMs. Blown out all the fuel lines, change the fuel filter. Ran half a can of liquid Molly diesel, purge direct into the engine to dissolve any gum up screens or anything like that. I’ve also checked and blown out all the vent lines for fuel. It seems to be starving for fuel, any ideas? What’s next?

Is there a coarse screen on the bottom in the fuel tank outlet?

Make sure it's not air starved, ck air filter.

Make sure the pedal is advancing the throttle

Thanks for the response, I’ve actually bypassed the fuel tank completely by running the intake hose into a clean gas can and have also bypassed the primer pump with no success, I’ve come to believe it’s somewhere between the primer pump and the engine/injector pump. This morning I’m going to take off the injector lines so I can get to the Fuel solenoid, remove it and see if it’s gummed up.

You might check if the exhaust is clear and not packed with mud
